Cough variant asthma may require long term treatment, if the therapeutic level is at level 1, no medication is needed, but long term monitoring and non-pharmacological interventions are still required, but long term medication may be needed for severe symptoms or recurrent attacks. Cough-variant asthma attacks can be better controlled when the patient is removed from allergens such as dust mites and treated with medications such as terbutaline. Terbutaline has a bronchodilating effect, and it is important to note that it is contraindicated in people who are allergic to this drug. Through the above treatment, most patients can control the symptoms and achieve clinical cure. Cough variant asthma may develop into refractory cough variant asthma with uncontrollable cough, wheezing and dyspnea when symptoms are severe or recurrent. At this point, long-term medication is needed, such as inhaled drugs like budesonide, which has a highly effective local anti-inflammatory effect. It should be noted that budesonide should be used with caution when the patient has a fungal, viral or tuberculosis infection in the airway. All of the above medications should be used under the guidance of a doctor, do not self-medicate. If the patient is not feeling well, he should go to the hospital in time, complete the relevant examination, under the guidance of the doctor to treat the symptoms, do not delay the condition.
